A group of men accused of raping a 19-year-old woman during the world-famous Pamplona bull-running festival recorded the horrific attack on a mobile phone, a court was told.

The five friends appeared before a Spanish court today and were remanded in custody pending further enquiries.

A judge said there was evidence to suggest the five "collectively participated in the violation" while it was recorded.

The five are being held on suspicion of sexual assault and robbery with violence or intimidation.

All of the men come from Seville and were visiting Pamplona for the San Fermin festival which attracts thousands of people from all over the world.

The accused are alleged to have approached the girl in one of the main plazas with the intention of taking her to their car.

However, along the way, the court was told, they pulled her into an archway and subjected her to "various sexual assaults", using their "physical superiority" to stop her calling for help.

Pamplona council has voiced its disgust and utter rejection of any form of violence against women.

It had already warned revellers to watch their behaviour because sexual assaults have plagued the celebrations in the past.

Last summer, there was a huge protest after a 19-year-old British woman was sexually assaulted by a group of men in a pub's toilets during the celebrations.

Groping bottoms and breasts has always been regarded as "acceptable" but tourism chiefs say this should not be the case and for this bull-running festival launched a major campaign throughout the city and online.

Women are even being issued with maps showing "danger hotspots" and warned to stay away from archways and the historic walls.

The council says that just because it is a fiesta, it does not mean that "anything goes" and nothing can justify sexual assaults or unwanted advances.

Extra police have been drafted in and CCTV cameras installed.

Officers will be patrolling isolated areas such as around the famous walls, parks and river banks.
